Tactics is more like Jagged Alliance 2/Commandos 2. I've finished it several times 'coz the gameplay is fun and the graphics are really good. If this game had come with a lot more npc's, dialogue and freedom, and had the developers known more about the Fallout setting, this could've been a worthy successor to FO2 'cause the story (save the BOS) and the gameplay (squad based tactical rpg) really go well together.
I´m gonna chime in as well, just to put the pressure on you: Give Tactics a shot, because it does feel as if it belongs to the franchise, in particular compared to Beth´s games. @Richwizard finish the damn game wtf!
